Auditing certificates
All actions that you perform on certificates are audited and can be viewed later. Note that reverting certificate changes is not possible. If you need to revert to a previous state, you'll have to delete a certificate and create a new one.
To audit certificates:
In the RAS Console, navigate to Farm > Site > Certificates.
Click Tasks > Settings audit.
The dialog opens where you can view the history of certificate actions. Note that the Revert button is disabled. As noted at the beginning of this section, reverting a certificate action is not possible.
To view details for a particular audit entry, double-click it.
